Protein attributes

Sequence length	582 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Neuronal phosphoprotein that coats synaptic vesicles, binds to the cytoskeleton, and is believed to function in the regulation of neurotransmitter release By similarity.
Subunit structure	Interacts with CAPON By similarity.
Subcellular location	Cell junction › synapse.
Tissue specificity	Central and peripheral nervous systems.
Domain	The A region binds phospholipids with a preference for negatively charged species By similarity.
Post-translational modification	Phosphorylation at Ser-10 dissociates synapsins from synaptic vesicles By similarity.
Sequence similarities	Belongs to the synapsin family.
Caution	There are several mRNAs and ESTs supporting this gene model. However, the genome sequence encoding the N-terminal part contains several sequence discrepancies.
Sequence caution	The sequence AC022234 differs from that shown. Reason: Frameshift at position 71. The sequence AC022234 differs from that shown. Reason: Several in-frame stop codons.
